Abstract
L'invention concerne un appareil et un procédé permettant un certaine diversité dans la réception d'une pluralité de signaux de radiodiffusion numérique. Un train constitué d'un ensemble complet de bits de code est généré par une ou plusieurs sources de bits de données. Un premier sous-ensemble critique de bits de code est choisi ou sélectionné pour un premier canal (par exemple, un motif de perforation spécifié est appliqué au train constitué de l'ensemble complet de codes). Un second (alternatif) sous-ensemble critique de bits de code est choisi ou sélectionné pour un second canal (par exemple, un second motif ou un motif alternatif de perforation est choisi pour le second canal). D'autres sous-ensembles critiques alternatifs peuvent être choisis pour tout autre canal supplémentaire. Tous les canaux sont des émetteurs, certains peuvent incorporer une fonction de retard pour permettre la réalisation d'une diversité temporelle. En outre, l'ordre d'émission des bits de code sur chaque canal peut être différent (par exemple, les profondeurs d'entrelacement peuvent être différentes). Au niveau du récepteur, les trains de sous-ensembles critiques de bits de code pour tous les canaux sont simultanément reçus, et un ensemble complet de bits de codes est reconstruit, lequel code reconstruit peut être inséré dans un décodeur Viterbi simple. L'invention concerne également diverses fonctions de pondération et divers algorithmes de reconstruction.
